Abstract
A projection display system includes a projector; a reflection screen for displaying images in a front projection system; a transmission screen for displaying images in a rear projection system; and a selective light projecting device for selectively directing the light from the projector to one of the reflection screen and the transmission screen, so as to perform switching between the front projection system and the rear projection system. The selective light projecting device may selectively change an optical path of image light from the projector between the reflection screen and the transmission screen, so as to direct the image light to one of the reflection screen and the transmission screen, or may selectively rotates a direction of a head of the projector between the reflection screen and the transmission screen, so as to emit the image light to one of the reflection screen and the transmission screen.
